Snoring-preventing smart mattress system

A smart mattress system for preventing snoring, the smart mattress system comprising:

• an air mattress (10) configured to self-adjust its own pressure and to measure the pressure in real time;
• a user terminal (30) receiving a set value or user information from a user and transmitting the set value or the user information to the air mattress (10);
• a server (50) having a sleep quality analyzing unit (55) receiving measurement data including pressure measurement value and pressure change amount from the air mattress (10) to analyze a sleep pattern and sleep quality of a user and determining a score of the sleep quality;
• and
• an air pillow (70) connected with the air mattress (10), the user terminal (30), and the server (50) and configured to self-adjust its own pressure,
• wherein the air mattress (10) includes:
• a microphone (22) measuring noise around the air mattress (10);
• and a snoring determination unit (23) determining whether the user is snoring, wherein
• when the noise is detected by the microphone (22), the snoring determination unit (23) checks an average change amount of a pressure change amount of an air pocket (110) of the air mattress (10) during a preset time range (T4), based on a noise detection time (T3) that the noise is detected, to determine whether the user is snoring,
• wherein the sleep quality analyzing unit (55) is configured to assign a score to each of ranges A, B, and C according to an average change amount of the pressure change amount of the air pocket (110), wherein a score a is assigned to the range A, a score b is assigned to the range B, and a score c is assigned to the range C, wherein,
• the range A is defined as the user being in a deep sleep (NREM sleep:
• non-rapid eye movement sleep) state, and the score a is 10 point,
• the range B is defined as the user being in a light sleep (REM sleep:
• rapid eye movement sleep) state, and the score b is 5 point, and
• the range C is defined as the user being in a wake state, and the score c is 1 point, wherein the scoring sleep quality is defined as follows:
• (a×T1)+(b×T2)+(c×T3)/T1+T2+T3, wherein,
• T1 is time for which the average change amount of the pressure change amount remains in the range A,
• T2 is time for which the average change amount of the pressure change amount remains in the range B, and
• T3 is time for which the average change amount of the pressure change amount remains in the range C.
